| D343H Flange type Three eccentric Multilayer Hard Seal Butterfly Valve | ||||||||||||
| It adopts precise J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure, and is widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction, etc. with medium temperature ≤425℃, for regulating flow and cutting off fluid. The valve adopts triple eccentric structure, the valve seat and the sealing surface of the disc are made of stainless steel with different hardness, which has good corrosion resistance and long service life. The valve has two-way sealing function, and the product meets the GB/T13927-92 valve pressure test standard. | ||||||||||||
| 特点 Characteristic | ||||||||||||
| 1. The valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has the sealing function of tightening as you look. | ||||||||||||
| 2. The seal ring is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance, long service life, etc. regardless of low temperature and high temperature. | ||||||||||||
| 3. The sealing surface of disc plate is made of hardfacing cobalt based carbide, which is wear resistant and has a long service life. | ||||||||||||
| 4. Quilting frame structure is adopted for large-sized butterfly plates, with high strength, large flow area and small flow resistance. | ||||||||||||
| 5. The valve has a two-way sealing function, and can be installed in any direction without the restriction of medium flow direction or the influence of space position. | ||||||||||||
| 6. The drive device can be installed in multiple stations (rotated by 90 ° or 180 °) for the convenience of users. | ||||||||||||
